Abstract

The utility model provides an internal connected safety anti-explosion warning device for tyres. The utility model is composed of a base block with a cross bore and a longitudinal screw which are connected with each other mutually in a cruciform shape, the air inflation inflating valve of the upper screw, a high and low air valves are respectively arranged on the base block of two sides of the lower screw, one end of the base block is convex, and the other end of the lower surface of the base block is communicated with the cross bore, and a whistle in a hollow adjusting bolt in the valves. In vehicle driving, when tyre pressure is too high or too low, the air flow passes through a high or a low pressure valves and runs out the whistle which sounds and alarms at the same time, then the vehicle is parking and processed, which ensures safety vehicle.

Description

Internal connected safety anti-explosion warning device for tyre

The utility model is about utilizing the mechanical type warning device of gas shock sounding component sounding, particularly about internal connecting type tire security personnel anti-explosion alarming device.

The vehicle tyre that moves on the road because tyre surface and sidewall are constantly upheld and compressed, makes between rubber molecule and the molecule, between cord and the rubber, between tire and the wheel rim and produce friction between tire and the road surface and give birth to heat.Especially at long-distance running, run at high speed, travelling on the rough road and when torridity summer travels, temperature can constantly raise, gas constantly expands in the tire, air pressure increases.When temperature, when air pressure surpasses certain limit, will blow out.In addition, vehicle is crossed when low when the too high or unexpected impaired air pressure that causes appears in a certain tire pressure under steam, and the air pressure of other tires and temperature are influenced by it will and produce rapid variation, its result will cause some change worst tire blast.On the present vehicle, all there are not the security personnel of tire and explosion-proof device, chaufeur under steam, the concrete situation of change that for various reasons can't the detail knowledge tire be in operation, for blowing out and simultaneous traffic accident of causing because of above-mentioned reason, sometimes or even the serious accident of car crash just can't know in advance, also can't take preventive measures in advance.Its result will inevitably cause painful cataphoretic failure.

The purpose of this utility model is to provide a kind of internal connecting type tire security personnel anti-explosion alarming device that can guarantee the vehicle tyre safety traffic.

The utility model has adopted following structural measure: at the longitudinal middle part of a matrix, being provided with one connects on the matrix, the screw of lower surface, this screwhole diameter size cooperates with tire valve, in the lateral middle of described matrix one cross-drilled hole that does not penetrate described matrix two side is set, this cross-drilled hole and described screw intersect vertically, and be divided into be interconnected on, following two parts, the aerating tire tube valve identical with tire valve (the upper end valve inside is partly schemed slightly) is set in the screw of described top, on the matrix of screw both sides, lower end symmetric position, respectively be provided with a straight hole that connects cross-drilled hole and matrix lower surface, in these two straight holes, be respectively arranged with by the tubulose valve body, steel ball and valve opening in the valve pipe, the height that spring that continues successively behind the steel ball and adjusting bolt constitute, low air pressure valve, described adjusting bolt is the tubulose of hollow, is provided with the flute whistle in this pore.Thereby realization the purpose of this utility model.

Regulate the spring pressure in the high and low air pressure valve in the utility model internal connecting type tire security personnel anti-explosion alarming device in advance, make their pressure equal the maximum and the minimum lower limit of tire pressure respectively.Unload the valve inside of former tire valve, directly to inflation of tire, when tire pressure reaches rated value, remove gas-adding pipe, meanwhile the bottom screw is screwed in tire valve rapidly with gas-adding pipe.This moment tire pressure and high and low air pressure valve medi-spring equilibrium of pressure.In the vehicle operating, when air pressure is too high in the tire, gaseous tension will be blocked the steel ball of valve opening and push open greater than anticyclonic pressure valve medi-spring pressure; Cross when low when tire pressure, the spring pressure in the low air pressure valve will be blocked valve opening greater than gaseous tension steel ball backs down; Steel ball is in case leave from valve opening, and air-flow is just gone out the adjusting bolt of hollow from cross-drilled hole through valve opening, valve pore, swashs and rings the warning of the flute whistle.Chaufeur should stop immediately and check, discharges fault, guarantees traffic safety.

Below with reference to the accompanying drawings embodiment of the present utility model is elaborated:

Fig. 1 is that the vertical profile of the utility model internal connecting type tire security personnel anti-explosion alarming device is looked scheme drawing, and this figure has also represented this device and the tire valve bonded assembly sample attitude of having removed valve inside.
